 `void TaskID` data typeWhat does "void" mean as a data type? I know what a "void" function is, but what does it mean when used as the name for a task? Is it just a string?
 Or is it a "void pointer", in which case I can treat it as a string?http://www.robotc.net/wiki/NXT_Function ... #StartTask On a slightly related note, is there a way to "fetch" the current task's ID? Line 274* of RobotCIntrinsics.c defines an `nCurrentTask`. Is this what I was looking for? Can I cast it to a "void" and pass it to the task-related functions? *: I'm using RobotC 3.60 due to some weird bugs, so this might not be correct. It's in the section "Read only operating system parameters". _________________ FTC Team 6424, the 'Oly Cow - Chief programmer. FRC Team 4450, Olympia Robotics Federation (ORF). and also quadrotors.

Re: `void TaskID` data type void means nothing. A void pointer is a pointer to a memory location of an unspecified type. A function with a void return type, returns nothing.

Re: `void TaskID` data type But, but... What does "void StartTask(void TaskID, const short nTaskPriority)" mean?

Re: `void TaskID` data type "void taskID" is the name of the task that you specified in your program:

Re: `void TaskID` data type So it's a string? Function pointer? Doohickey?
